A molecule is formed when two or more atoms join together chemically. A compound is a molecule that contains at least two different elements. All compounds are molecules but not all molecules are compounds.

Sickle cell disease (SCD) is caused by a recessive version of the hemoglobin gene. In the US, SCD occurs in about 0.2% of the ne

Answer:

Number of babies with dominant hemoglobin genotype will be $9120$

Explanation:

Given -

$0.2$ % of babies have SCD which means they have recessive version of hemoglobin

Let the recessive version of hemoglobin be represented by "h" and normal version of hemoglobin be represented by "H"

Babies having SCD will have genotype "hh" i.e homozygous recessive.

As per Hardy Weinberg's equation -

$q^2= 0.002$

Thus, frequency of allele for recessive version of hemoglobin (h) is

$\sqrt{q^2} \\= \sqrt{0.002} \\= 0.045\\$

Frequency of allele for normal version of hemoglobin (H) is

$1-0.045\\= 0.955$

Thus, Frequency of population with normal version of hemoglobin i.e HH is equal to

$p^{2}$

$= 0.955^2\\= 0.912$

hence, number of babies with dominant hemoglobin genotype will be

$0.912 * 10000$

$= 9120$
